nerves are fine, sliglitly darker than the disc. Legs pale brownish ; thighs pale 

 brownish, all the pairs next the apex darker, sometimes almost black ; tibice 

 more or less pale brownish, all the pairs with a small black spot exteriorly at the 

 base ; 3rd pair generally fuscous-black, except a narrow pale margin round the 

 black spot at the base, spines pale yellowish or whitish ; tarsi pale yellowish- 

 white ; 1st joint, apical half, and 2nd brownish ; 3rd black. 



Abdomen above and beneath, black, posterior margins of the segments narrowly 

 gi'cenish, becoming yellow after death ; last genital segment black, posterior 

 margin pale brownish-yellow ; external processes pale brownish-yellow. 



$ frequently as dark coloured as the $ , or fulvous or testaceous ; in dark specimens 

 the apex of the 3rd pair of thighs and tibiae (except around the spot at the 

 base) black, in pale examples the legs are entirely yellowish ; all the tibiae, with 

 the usual black spot at the base, and the apex of the last joint of the tarsi black. 



Abdomen imderneath, in life pale greenish, with a somewhat silvery appearance ; 

 after death yellow. Length, c? , 1 ^ ; ? , 2 hues. 



Allied to p. tilice, but it is smaller than tliat insect, and lias not 

 its green head, pronotum and scutellum, nor the spotted apical areas 

 of the membrane. In repose, the (^ has a peculiar dark appearance 

 between the base o£ the elytra and the apex of the clavus, owing to 

 the abdomen shining through ; and, in one of my specimens, I observe 

 that the whole of the nerves have a fuscous margin on either side, 

 and the apical areas pale. I have compared it with the descriptions 

 of P. glandacia and fuscula of Fiebei', to which section it belongs, 

 but it does not agree with either. 



Very common on elms in July and August : taken by Mr. 

 Douglas and myself at Lee.
